The electronic mail program 54A is a program for sending and receiving communication messages from a communication line such as a telephone line 76 via a modem 75, to be described later, by means of the internet. The electronic mail program 54A has the function of delivered mail acquisition. Under the delivered mail acquisition function, the user inquires of a mail server 78 owned by an internet service provider 77 whether a mail box 79 has received mails directed to the user, and acquires mails in case there are such mails.

The auto pilot program 54B sequentially initiates preset plural items of precessing (or plural programs) in a preset order, and executes the processing or programs.

The OS (basic program software) 54E such as Windows 95 and 98 (both registered trade mark) manufactured by Microsoft Corporation, Mac OS (registered trade mark) manufactured by Apple Computer Inc. etc. controls basic operation of a computer.

The jog dial state monitoring program 54C receives information of jog dial adaptability from the respective applications, and in case the application is jog-dial-adaptable, the jog dial state monitoring program 54C displays what can be performed on operating the jog dial 4. Normally, the jog dial state monitoring program 54C is in the state of waiting for the event of the jog dial 4, and has a list of information to be received from the applications. The jog dial driver 54D performs various functions corresponding to the operation of the jog dial 4.

As the application software for picture viewer & picture reformation processing referred to as the application program 54F₁, Picture Gear (registered trade mark) can be exemplified, specifically. The Picture Gear is software which can concentratively manages moving picture data and still picture data stored in various removable media such as a hard disc, floppy disk, MO, PC card, and other card-shaped memories. Respective pictures can be displayed in a list by a predetermined operation, which enables the user to visually find out a subject picture. By performing picture reformation processing, a panoramic picture of 360 degrees and a label having a photo can be formed. Furthermore, an HTML album whose pictures can be seen by means of a WWW browser can also be formed. The details will be described later.

A video controller 57 is connected to the PCI bus 56, and controls the displaying operation of the LCD 7 arranged on the display unit 3 based on data supplied via the PCI bus 56.

A sound controller 64 is connected to the PCI bus 56, which receives audio signals from a microphone 66 and send audio signals to a speaker 65. A modem 75 is also connected to the PCI bus 56. The modem 75 can be connected to a communication network such as the internet 80 and the mail server 78 via the telephone line 76 and internet service provider 77.

The south bridge 58 is also connected to the PCI bus 56. The south bridge 58 such as a PIIX4E manufactured by Intel Corporation controls various I/O (Input/Output). That is, the south bridge 58 is composed of an IDE (Integrated Drive Electronics) controller/configuration register 59, a timer circuit 60, and an IDE interface 61, which controls devices connected to an IDE bus 62, devices connected to an ISA/EIO (Industry Standard Architecture/Extended Input Output) bus 63, and devices connected to an embedded controller 68.

The IDE controller/configuration register 59 is composed of two IDE controllers or a primary IDE controller and a secondary IDE controller, a configuration register, etc. not shown.

The primary IDE controller is connected to a connecter, not shown, via the IDE bus 62, and the HDD 67 is connected to the connecter. Also, the secondary IDE controller is connected to bay devices as IDE devices such as a CD-ROM drive, a second HDD, an FDD, not shown, via another IDE bus, etc. When such bay devices are connected to the secondary IDE controller, connecters of the bay devices are electrically connected to the secondary IDE controller.

The HDD 67 stores an electronic mail program 67A, an auto pilot program 67B, a jog dial state monitoring program 67C, a jog dial driver 67D, an OS (basic program software) 67E, other application programs 67F₁˜67F_(n), etc. in advance. The application program 67F₁ is the application software for picture viewer & picture reformation processing such as the Picture Gear. Thus, the HDD 67 is a specific example of a program storage medium according to the present invention.

The respective programs 67A, 67B, 67C, 67D, 67E, 67F₁˜67F_(n) in the HDD 67 are sequentially transferred to the main memory 54 in the initiation (boot up) processing, and the programs are temporarily stored in the main memory 54 as the electronic mail program 54A, an auto pilot program 54B, a jog dial state monitoring program 54C, a jog dial driver 54D, an operating program (OS) 54E, other application programs 54F₁˜54F_(n), etc.

The embedded controller 68 is also connected to the ISA/EIO bus 63. The embedded controller 68 is a micro controller, and is used as an I/O controller. That is, an I/O interface 69, a ROM 70, a RAM 71, a CPU 72 are mutually connected to each other to configure the embedded controller 68.

An LED control program 70A, a touch pad input monitoring program 70B, a key input monitoring program 70C, a wake up program 70D, a jog dial state monitoring program 70E are stored in the ROM 70.

The LED control program 70A is a program for controlling the lighting of the power lamp PL, battery lamp BL, message lamp ML if necessary, and other lamps, which are LEDs. The touch pad input monitoring program 70B is a program for monitoring input operation by the user from the touch pad 6. The key input monitoring program 70C is a program for monitoring input operation by the user from the keyboard 5 and other key switches. The wake up program 70D is a program for checking the current time data supplied from the timer circuit 60 in the south bridge 58 with the preset time, and managing respective chip power supplies so as to initiate predetermined processing (or programs) when the current time corresponds with the preset time.

The jog dial state monitoring program 70E is a program for monitoring the state of the jog dial 4, and checks if the jog dial 4 is rotated or pressed.

The ROM 70 stores a BIOS (Basic Input/Output System) 70F. The BIOS is a basic input/output system, and is a software program for controlling data receiving/sending (input/output) among the OS, application software, peripheral devices (display, keyboard, HDD, etc.)

A RAM 71 has registers 71A˜71F for LED controlling, touch pad input status, key input status, time setting up, jog dial state monitoring, etc. For example, an LED controlling register 71A controls the lighting of the message lamp ML, to be described later, for indicating the instant rising state of an electronic mail after the jog dial 4 is pressed. A key input status register 71C stores an operation key flag when the jog dial 4 is pressed for one-touch operation, to be described later. A time setting up register 71D can set up the time arbitrarily.

Furthermore, the jog dial 4, touch pad 6, keyboard 5 are connected to the embedded controller 68 via connecters, not shown. The embedded controller 68 sends signals corresponding to the respective operations of the jog dial 4, touch pad 6, keyboard 5 to the ISA/EIO bus 63. Also, the power lamp PL, battery lamp BL, message lamp ML, and other lamps, which are LEDs, are connected to the embedded controller 68.

Furthermore, a power supply controlling circuit 73 is connected to the embedded controller 68. The power supply controlling circuit 73 is connected to a built-in battery 74 or an AC power supply, which supplies necessary power to respective units, and controls charging of the built-in battery 74 and second batteries of peripheral devices. Also, the embedded controller 68 monitors a power switch 8 which is operated when the power is turned on or off.

Furthermore, an IEEE 1394 port 26 is connected to the embedded controller 68. So, the note-type personal computer 1 can receive video data from the digital video camera 35 via the IEEE 1394 cable 9 which is connected to the IEEE 1394 port 26.

Next, the configuration of a picture viewer & picture reformation processing system which consists of the note-type personal computer 1, internet 80, and a picture server 100 will be explained with reference to FIG. 3.

One example of the picture server 100 is a server for use in Image Station (trade mark) which was established as an image sharing service.

The Image Station is a new network service using moving pictures and still pictures. The user can preserve moving pictures and still pictures in an album by having an access to the site of the Image Station to perform member registration, and uploading the moving picture data and still picture data of the user from his personal computer. The user can see thus preserved pictures, and can send the picture data from his personal computer. Also, the user can make the album public, and can upload the picture data to an album which is owned jointly by users having the same hobby or taste. Thus, the network service can be used for communication among such users.

Conventionally, when uploading picture data to the internet, the user is required to have the knowledge of processing concerning the Web site construction and the network construction. On the other hand, when the Image Station employs the information processing apparatus and method according to the present invention, the user can upload picture data on desktop of his personal computer by relocating the picture into an icon for drag-and-drop in the site of the Image Station. Furthermore, downloading can be performed by simple processing.

On the other hand, what is connected to the note-type personal computer 1 is not limited to the picture server 100, and an HDD of large capacity or another storage such as a recording medium can be connected to the note-type personal computer 1.

The note-type personal computer 1 has the LCD 7 for displaying information stored in an internal storage provided therein, and an external storage or the external picture server 100 connected thereto, via the internet 80. And, operation for the information stored in the respective storages is performed by the user in the same procedure using operation units such as the keyboard 5, touch pad 6, with indication on the LCD 7 confirmed.

When the information stored in the picture server 100 is displayed, the LCD 7 displays auxiliary information indicative of this notice. The LCD 7 displays the auxiliary information using a different folder name, or displays the auxiliary information on the background of a display area of the LCD 7.

In the picture viewer & picture reformation processing system shown in FIG. 3, a Picture Gear window 201 displayed on the LCD 7 of the note-type personal computer 1 (local computer) displays information concerning the contents stored in the internal storage of the note-type personal computer 1, and other information concerning the contents sent from the picture server 100, as shown in FIG. 4. In this way, the picture viewer & picture reformation processing system can display multimedia contents via the internet such as picture information in a simplified manner without troubling or burdening the user, similar to the operation for displaying picture information stored in the internal storage.

Next, an operation for acquiring contents on a network of an information processing system such as the picture viewer & picture reformation processing system will be explained with reference to FIG. 5. In FIG. 5, the application software for picture viewer & picture reformation processing is shown as client application software, while the picture server 100 is shown as server module.

The client application software includes connection step of making a communication connection to the picture server 100 connected to the note-type personal computer 1 via the internet 80, selection step of selecting picture information stored in the picture server 100, whose communication connection with the note-type personal computer 1 is secured by way of the connection step, by displaying the information on the LCD 7 and using the operation units, similar to the operation for displaying the picture information stored in the internal storage, and information acquisition step of acquiring picture information selected from the picture server 100 in the selection step.

Specific example of the connection step is authentication processing of the user in step S1, which step is to be described later. Specific examples of the selection step are processing for enumerating directories in step S2, processing for acquiring contents in step S3, and processing for acquiring minimum information in step S4, which steps are to be described later. Specific example of the information acquisition step is processing for acquiring contents in step S5.

First, in step S1, the note-type personal computer 1 performs authentication processing of the user by executing the client application software. In the following explanation, it is considered that the client application software is executed by the note-type personal computer 1. The authentication processing of the user is performed when the user sends account, password, etc. After the authentication processing is completed, the server module sends a message that the server module has authenticated the user to the client application software.

Next, the client application software executed by the note-type personal computer 1 requires the server module to send a directory list, or list of directories, thereto so as to find a place (referred to as directory, hereinafter) where contents peculiar to the user or contents owned jointly by a specific group. Responding to the request, the server module sends a directory list to the client application software. Then, in step S2, the client application software displays the directory list and enumerates directories to the user, and makes the user select a directory whose contents the user wants to confirm. At this time, the client application software concurrently displays a directory list concerning the contents stored in the internal storage on a presentation area 202 for presenting directories, to be described later.

FIG. 6 shows a specific example of directories, from which the user selects one directory, and confirms the contents thereof. The Picture Gear window 201 is composed of the presentation area 202 for presenting directories, a picture display area 203, and another picture display area 204, in which pictures are displayed with their sizes highly reduced. The picture display area 203 displays many zoomed pictures of arbitrary size in the form of a list (sheet view displaying). When displaying all the pictures, picture display area 204 with high reduction degree can be used. Only one picture selected from the sheet-view-displayed pictures can be displayed on the picture display area 203. Sizes of pictures in the picture display area 203 and the picture display area 204 can be expanded/reduced by a slide operation unit 205 with a gage for zoom in/out operation. A picture, or pictures which are sheet-view-displayed in the form of a list can be zoomed in/out with high speed in the range, for example, from 12.5% to 800%.

In the presentation area 202, so as to definitely distinguish a folder in the internal storage of the note-type personal computer 1 from that in the external storage or server module connected to the note-type personal computer 1 via the internet, the internal folder is shown simply as “folder”, while the external folder is shown as “external connection”. In FIG. 6, contents in the internal “folder” are displayed on the picture display area 203. In case of selecting the “external connection”, the user is required to select desired folder (folder A or folder B) from a detailed presentation area 202 a for the external folders.

When the folder B is selected, the client application software requires the server module to send a contents list, or list of contents, thereto, which exists in the directory of the folder B. When the server module sends a contents list responding to the request, in step S3, the client application software can acquire the contents list.

Then, in step S4, the client application software requires the server module to send part of all the respective contents acquired in the step S3 thereto so as to acquire minimum information of the contents. Responding to the request, the server module sends part of the respective contents. The minimum information is thumbnails of pictures or one frame of moving pictures.

FIG. 7 shows thumbnail pictures 206 displayed on the picture display area 203 by the client application software. By taking a look at the thumbnail pictures 206, the user can grasp the contents before acquiring the contents, which enables the user to obtain the standard for judgement to select necessary data. This processing is performed actively by the application software without the user's operation. Thus, the user can grasp the contents by only selecting a directory in which the contents exist. At this time, the picture display area 203 displays auxiliary information 207 indicative of the Image Station on the background of the thumbnail pictures 206. This intends to distinguish the displaying manner for pictures of the internal storage from that for pictures of the Image Station, which displaying manners are similar to each other.

When the client application software acquires the minimum contents information in step S4 and displays the thumbnail pictures 206 on the picture display area 203, and the user decides to acquire picture data after taking a look at the thumbnail pictures 206, then in step S5, the application software requests the server module to send contents of the picture data thereto corresponding to the operation of the user. Then, the client application software acquires all the contents in case the contents are sent from the server module. This operation is similar to that for acquiring contents stored in the internal storage of the local computer. This operation means copying files, displaying pictures, etc.

Next, an operation for sending contents to the network of the information processing system will be explained with reference to FIG. 8. As shown, there are performed authentication processing of the user in step S11, processing for enumerating directories in step S12, processing for acquiring contents in step S13, and processing for acquiring minimum information in step S14, which processing steps are similar to those of step S1 to step S4 shown in FIG. 5.

Then in step S15, the client application software transfers contents stored in the local computer (note-type personal computer 1) of the user to the server module. This operation is similar to that for processing contents stored in the internal storage of the local computer. That is, specifically, pasting files, drag-and-drop operation, etc. In more detail, the user opens local folders stored in the internal storage on the presentation area 202 of a directory in the Picture Gear window 201 shown in FIG. 6, and displays contents pictures on the picture display area 203. Then, the user select desired picture from the contents pictures, and performs drag-and-drop operation for the selected picture to relocate the picture into a folder of the Image Station presented on the presentation area 202.

According to the note-type personal computer 1 incorporated into the picture viewer & picture reformation processing system, contents which actually do not exist in the personal computer can be presented to the user as if the contents exist in his personal computer. Thus, the user can deal with contents on the network in a manner similar to that for dealing with contents in a local computer which the user is accustomed to using. So, user interface (UI) can be unified, which can reduce operations that the user have to learn.

The note-type personal computer 1 reads out the application software for picture viewer & picture reformation processing shown in FIG. 5 and FIG. 8 from a program storage media such as an HDD, and causes the application software to be executed by a CPU. When a picture viewer & picture reformation processing apparatus is configured by using only hardware, the apparatus becomes complicated and enlarged in size. So, the configuration of the hardware of the note-type personal computer 1 can be simplified.

As in the above, the picture viewer & picture reformation processing system processes picture information such as moving pictures and still pictures. On the other hand, as the information, music information and text information is possible.

For example, when processing music information, in step S4 shown in FIG. 5, title names and artist names of the music information may be displayed, or intro of a few seconds may be played.
